I confess to a certain fond recollection of Neil Diamond, as well.
My brother, a rather talented musician, just recorded a cover of "Stayin' Alive" that I rather liked, using electric guitar and his regular singing voice, rather than falsetto. Kind of a "metal" interpretation. I thought it was pretty good, actually. But then, my memories of the Bee Gees don't pain me the way the seem to affect some of the rest of you, even if I do prefer Joan Baez (or Tommy Sands).
